iphone - iOS 5 で NSDateFormatter が nil を返す

Question

iOS 6 ではすべて問題ありませんが、iOS 5 では myDate は nil を返します

NSString *dateString = @"2012-07-12T11:00:00+02:00";

NSLocale *deLocale = [[NSLocale alloc] initWithLocaleIdentifier:@"de_DE"];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"YYYY-MM-dd'T'HH:mm:ssZZZZ"];
dateFormatter.locale = deLocale;
NSDate *myDate = [dateFormatter dateFromString:dateString];

それは私が信じているDateFormatの問題であるに違いありません

Answer 1

NSDate *today = [NSDate dateWithTimeIntervalSinceNow:0];
 NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
 [dateFormat setDateStyle:NSDateFormatterShortStyle];
 NSString *dateString = [dateFormat stringFromDate:today];
 NSLog(@"Date: %@", dateString);

Answer 2

これは私のために働きます：

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"dd/MM/yyyy hh:mm:ss a"];
NSLog(@"%@", [dateFormatter dateFromString:@"12/12/2012 12:12:12 AM"]);
